Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518684, here are decompositions:

73 + 518611 = 518684
97 + 518587 = 518684
151 + 518533 = 518684
163 + 518521 = 518684
211 + 518473 = 518684
373 + 518311 = 518684
547 + 518137 = 518684
571 + 518113 = 518684

Showing the first eight; more decompositions exist.
